i `'Be it known that LANDREW Dm'rz, of the eity, i county, and State of New York, have invented a new and useful Improvement `in Crushers, of which the following is a full, clear,l andl` exact description-,T refer- `ence beinghadtothe accompanying drawing forming part of this specification, and in which- Figure 1 represent-s a sectional elevation of crusher constructed in accordancewithfmy invention, and

2, a horizontal' section through the. line a: a:

Siniilarletters of reference indicate corresponding My'invention relates to machines for `breaking 'stonesand other` substances, and will befonnd advantageously applicable tbreaking or reducing brickbat-s for the purpose of ntilizingthe same 'by their y remannfactnre into brick. j

'lhenvention consists in a certain combination and arrangement of areciprocating tapering breaker haw' ing `teeth or ri'bsonits sideor sides, a revolving c 'ank oreccentric andwrod for operating the' breaker, and a t toothed or ribbed fixed surface or surfaces also set ta- "pering or oblique tothe. line of `the breakers' motion,-

'bnt at a` different angle to the ribbed `surface of the latter, so that it'will forinfadiminishing space or 'channelin a downward direction between it and the t breaker. r i

1 IMPROVEMENT IN sToNE-CRUSHERS.

'The Schedule rferred to in these Letters Patent and z'naking part bf the same.

'IIhe breaker. B is of tapering contiguration onits side or sides, conveying in a downward direction toward'itsV axis or general line of motion, and being stepped, toothed, or ribbed, preferably in directions at right angles, or thereabont, "to the length of the. breaker. v' Y The crushing-roceptacle G, in which tbe breaker works, is also made taperingon its insidev face or faces',-convergiug in a downward dirction'toward the axis Vof the breaker, but at a different angie' to the ribbed surface'of the latter,' so as to lforni a wider ceptacle, which latter is likewiset'oothed or ribbed internally, and is open above and below to receive and :discharge tb'e material under operation.

To break 0r crush the stone, brick, or other substance, it is only necessary to feed or throw the' same into the receptacleat the top, when the reciprocating action of the toothed breaker, acting1'in concert with the tootbedreceptacle or stationary surface, both set tapering or obliquely'in relation to eachother and the .tiresubstance to 'be gradually Vbroken smaller and stnaller, each successive stamping action of .the breaker as lproduced by its tapering side or sides in opposition to the tapering side or sides of the receptacle, and the breaker in its ascent readily freeing itself and allowing of the easy`feedor drop of the substance down the crushing-receptacle.

What is here claimed, and desired to be secured by Letters Patent', is v eating taperingand toothed or'ribbed breaker B, the 4crank or eccentric d on the revolving: shaft e, the rod f, and the stationary tapering and toothed or ribbed outer surface or' receptacle G, substantially as shown and described.
